Supplier provenance ledger
Hypothetical. Not a client, not a result.
// The problem
A prime and its tier suppliers exchange certificates of conformance and test reports by email, and confirming that a part is genuine and traceable depends on finding the right attachment.
// What we would build
A supplier portal where certificates and test reports are uploaded against purchase orders and serial numbers, recorded on a private permissioned ledger that the prime and its main suppliers each run a node of, so the provenance record cannot be quietly edited. If the prime's own records are trusted by all, a database is cheaper, and we will say so.
// What is in it
- Certificates and test reports uploaded against purchase orders and serials
- Each document fingerprinted and recorded on a private chain with a node per party
- Provenance from a part back to the original manufacturer's certificate
- Alerts when a certificate is missing, expired or does not match
- Hosted in the prime's own cloud tenant in a Canadian region
// Stack
- Next.js
- Hyperledger Besu (private, permissioned)
- PostgreSQL
- Azure Canada
